Dr. Sahni's research is focused on formulation and application of advanced numerical methods and tools for complex fluid flow problems with a focus on turbulence, flow control and unsteady aerodynamics. Specifically, for flow problems that exhibit multiscale phenomena and are of stochastic nature due to uncertain inputs. His expertise is on high-fidelity simulation methods and tools including scale-resolving simulation techniques such as large eddy simulation and direct numerical simulation. His research places emphasis on multiscale methods, complex geometry and unstructured meshes, anisotropic adaptive procedures, uncertainty quantification, and high performance computing.
Large eddy simulation of flows involving unsteady aerodynamics related to surging and/or pitching motions as well as active control techniques such as fluidic actuation (synthetic jets) and shape modification (e.g., active cambering).
